Passively Learning Finite Automata

Kevin P. Murphy

Working Papers from Santa Fe Institute

Abstract: We provide a survey of methods for inferring the structure of a finite automaton from passive observation of its behavior. We consider both deterministic automata and probabilistic automata (similar to Hidden Markov Models). While it is computationally intractible to solve the general problem exactly, we will consider heuristic algorithms, and also special cases which are tractible. Most of the algorithms we consider are based on the idea of building a tree which encodes all of the examples we have seen, and then merging equivalent nodes to produce a (near) minimal automaton.
